WIRE HARNESS
A wire harness including: a wire; a cover that covers the wire; and a braid made of resin that covers the wire, wherein: the wire protrudes from a first end of the cover to an outside of the cover, and a space is formed between the wire and the first end, and the braid is provided at a position that overlaps the first end of the cover in a longitudinal direction of the wire and is exposed to the outside of the cover.
Warning device for preventing underground cables against accidental excavation
A warning device for preventing underground cables against accidental excavation comprises an optical fiber vibration sensor having a mode recognition function, a signal processing unit, a wireless communication unit and a power supply unit, wherein the signal processing unit is connected to the optical fiber vibration sensor, the wireless communication unit and the power supply unit, and the optical fiber vibration sensor is installed within a set range of a cable and is used to monitor vibration signals around the cable, so that once a behavior possibly endangering the cable occurs, an alarm is given out in time to reduce power transmission and transformation accidents. Compared with the prior art, the warning device has the advantages of low false alarm rate, rapid response and accurate localization region.
Wire exterior body and exterior-covered wire harness
A wire exterior body and an exterior-covered wire harness in which damage by an attaching member is prevented are provided.

Cable and producing method therefor
A cable is composed of a linear shape conductor, a first electrical insulating member coating a periphery of the conductor, a shield made of a plating layer coating a surface of the first electrical insulating member, a second electrical insulating member coating a surface of the shield, and an exposed shield portion provided in at least one end portion of the cable with the second electrical insulating member being removed therefrom and the shield being exposed therein during termination. An adhesion strength between the shield and the second electrical insulating member in the exposed shield portion is lower than an adhesion strength between the shield and the second electrical insulating member in an other part of the surface of the shield.
SYSTEMS, METHODS AND TOOLS FOR THE INTERROGATION OF COMPOSITE STRENGTH MEMBERS
Systems, methods and tools for the interrogation of fiber-reinforced composite strength members to assess the structural integrity of the strength members. The systems and methods utilize the transmission of light through optical fibers that are embedded along the length of the strength members. The inability to detect light through one or more of the optical fibers may be an indication that the structural integrity of the A strength member is compromised. The systems and methods may be implemented without great difficulty and may be implemented at any time in the life cycle of the strength member, from production through installation. The systems and methods have particular applicability to bare overhead electrical cables that include a fiber-reinforced strength member.
COMMUNICATION CABLE
A communication cable contains: at least one signal line including a pair of insulated wires placed side by side, each insulated wire having a conductor and an insulation covering which covers the conductor; a shielding body which covers the at least one signal line; a sheath which covers the shielding body; and a bend restricting member which restricts bending of the at least one signal line in a lateral direction a which is a direction along which the pair of insulated wires are placed side by side, as compared with bending of the at least one signal line in a vertical direction intersecting the lateral direction.
Periodic transmission line cable filtering
A differential transmission line cable includes a notch filter to manage common-mode energy. The cable includes a narrow portion with two adjacent electrical conductors each having a narrow cross-sectional area and spaced at a narrow spacing. The cable also includes a wide portion longitudinally adjacent to the narrow portion. The wide portion includes the two adjacent electrical conductors each having a wide cross-sectional area greater than the narrow cross-sectional area and spaced at a wide spacing greater than the narrow spacing. The wide and narrow cross-sectional areas and spacings are specified so that the differential-mode impedance of the differential transmission line cable is uniform throughout both the narrow and wide portions and so that differences in the common-mode impedances of the narrow and wide portions create a notch filter to manage common-mode energy in the differential transmission line cable.
